Distinguishing Clinical From Statistical Significances in Contemporary Comparative Effectiveness Research.

OBJECTIVE: To determine the prevalence of clinical significance reporting in contemporary comparative effectiveness research (CER). BACKGROUND: In CER, a statistically significant difference between study groups may or may not be clinically significant. Misinterpreting statistically significant results could lead to inappropriate recommendations that increase health care costs and treatment toxicity. METHODS: CER studies from 2022 issues of the Annals of Surgery , Journal of the American Medical Association , Journal of Clinical Oncology , Journal of Surgical Research , and Journal of the American College of Surgeons were systematically reviewed by 2 different investigators. The primary outcome of interest was whether the authors specified what they considered to be a clinically significant difference in the "Methods." RESULTS: Of 307 reviewed studies, 162 were clinical trials and 145 were observational studies. Authors specified what they considered to be a clinically significant difference in 26 studies (8.5%). Clinical significance was defined using clinically validated standards in 25 studies and subjectively in 1 study. Seven studies (2.3%) recommended a change in clinical decision-making, all with primary outcomes achieving statistical significance. Five (71.4%) of these studies did not have clinical significance defined in their methods. In randomized controlled trials with statistically significant results, sample size was inversely correlated with effect size ( r = -0.30, P = 0.038). CONCLUSIONS: In contemporary CER, most authors do not specify what they consider to be a clinically significant difference in study outcome. Most studies recommending a change in clinical decision-making did so based on statistical significance alone, and clinical significance was usually defined with clinically validated standards.

Predictors of Venous Thromboembolism After Lung Cancer Resection.

BACKGROUND: Venous thromboembolism (VTE) is a major cause of morbidity and mortality in patients undergoing oncologic operations. We sought to identify risk factors for postoperative VTE to define high-risk groups that may benefit from enhanced prophylactic measures. METHODS: A retrospective cohort analysis using The Society of Thoracic Surgeons General Thoracic Surgery Database was conducted on patients who underwent lung cancer resection between 2009 and 2021. Baseline characteristics and postoperative outcomes were compared between patients who did and did not develop a postoperative pulmonary embolism (PE) or deep venous thrombosis. Multivariable regression models identified risk factors associated with VTE. RESULTS: Of 57,531 patients who underwent lung cancer resection, a postoperative PE developed in 758 (1.3%). Patients with PE were more likely to be Black (12% vs 7%, P < .001), have interstitial fibrosis (3% vs 2%, P = .016), and prior VTE (12% vs 6%, P < .001). Postoperative PE was most likely to develop in patients with locally advanced disease who underwent bilobectomy (6% vs 4%, P < .001) or pneumonectomy (8% vs 5%, P < .001). Patients with postoperative PE had increased 30-day mortality (14% vs 3%, P < .001), reintubation (25% vs 8%, P < .001), and readmission (49% vs 15%, P < .001). On multivariable analysis, Black race (odds ratio, 1.74; 95% CI, 1.39-2.16; P < .001), interstitial fibrosis (odds ratio, 1.77; 95% CI, 1.15-2.72; P = .009), extent of resection, and increased operative duration were independently predictive of postoperative PE. A minimally invasive approach compared with thoracotomy was protective. CONCLUSIONS: Because nonmodifiable risk factors (Black race, interstitial fibrosis, and advanced-stage disease) predominate in postoperative PE and VTE-associated mortality is increased, enhanced perioperative prophylactic measures should be considered in high-risk cohorts.

Health Care Costs Following Anterior Cervical Discectomy and Fusion or Cervical Disc Arthroplasty.

STUDY DESIGN: Observational cohort study. OBJECTIVE: To describe the postoperative costs associated with both anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) in the two-year period following surgery. SUMMARY OF BACKGROUND DATA: CDA has become an increasingly common alternative to ACDF for the treatment of cervical disc disorders. Although a number of studies have compared clinical outcomes between both procedures, much less is known about the postoperative economic burden of each procedure. MATERIALS AND METHODS: By analyzing a commercial insurance claims database (Marketscan, Merative), patients who underwent one-level or two-level ACDF and CDA procedures between January 1, 2017 and December 31, 2017 were identified and included in the study. The primary outcome was the cost of payments for postoperative management in the two-year period following ACDF or CDA. Identified postoperative interventions included in the study were: (i) physical therapy, (ii) pain medication, (iii) injections, (iv) psychological treatment, and (iv) subsequent spine surgeries. RESULTS: Totally, 2304 patients (age: 49.0±9.4 yr; male, 50.1%) were included in the study. In all, 1723 (74.8%) patients underwent ACDF, while 581 (25.2%) underwent CDA. The cost of surgery was similar between both groups (ACDF: $26,819±23,449; CDA: $25,954±20,620; P =0.429). Thirty-day, 90-day, and two-year global costs were all lower for patients who underwent CDA compared with ACDF ($31,024 vs. $34,411, $33,064 vs. $37,517, and $55,723 vs. $68,113, respectively). CONCLUSION: Lower two-year health care costs were found for patients undergoing CDA compared with ACDF. Further work is necessary to determine the drivers of these findings and the associated longer-term outcomes.

Impact of Median MELD at Transplant Minus 3 National Policy on Quality of Transplanted Livers for Patients With and Without Hepatocellular Carcinoma.

BACKGROUND: Patients with hepatocellular carcinoma (HCC) have been overprioritized in the deceased donor liver allocation system. The United Network for Organ Sharing adopted a policy in May 2019 that limited HCC exception points to the median Model for End-Stage Liver Disease at transplant in the listing region minus 3. We hypothesized this policy change would increase the likelihood to transplant marginal quality livers into HCC patients. METHODS: This was a retrospective cohort study of a national transplant registry, including adult deceased donor liver transplant recipients with and without HCC from May 18, 2017, to May 18, 2019 (prepolicy) to May 19, 2019, to March 1, 2021 (postpolicy). Transplanted livers were considered of marginal quality if they met ≥1 of the following: (1) donation after circulatory death, (2) donor age ≥70, (3) macrosteatosis ≥30% and (4) donor risk index ≥95th percentile. We compared characteristics across policy periods and by HCC status. RESULTS: A total of 23 164 patients were included (11 339 prepolicy and 11 825 postpolicy), 22.7% of whom received HCC exception points (prepolicy versus postpolicy: 26.1% versus 19.4%; P = 0.03). The percentage of transplanted donor livers meeting marginal quality criteria decreased for non-HCC (17.3% versus 16.0%; P < 0.001) but increased for HCC (17.7% versus 19.4%; P < 0.001) prepolicy versus postpolicy. After adjusting for recipient characteristics, HCC recipients had 28% higher odds of being transplanted with marginal quality liver independent of policy period (odds ratio: 1.28; confidence interval, 1.09-1.50; P < 0.01). CONCLUSIONS: The median Model for End-Stage Liver Disease at transplant in the listing region minus 3 policy limited exception points and decreased the quality of livers received by HCC patients.

Sex-based Disparities in Access to Liver Transplantation for Waitlisted Patients With Model for End-stage Liver Disease Score of 40.

OBJECTIVE: To determine the association of sex with access to liver transplantation among candidates with the highest possible model for end-stage liver disease score (MELD 40). BACKGROUND: Women with end-stage liver disease are less likely than men to receive liver transplantation due in part to MELD's underestimation of renal dysfunction in women. The extent of the sex-based disparity among patients with high disease severity and equally high MELD scores is unclear. METHODS: Using national transplant registry data, we compared liver offer acceptance (offers received at match MELD 40) and waitlist outcomes (transplant vs death/delisting) by sex for 7654 waitlisted liver transplant candidates from 2009 to 2019 who reached MELD 40. Multivariable logistic and competing-risks regression was used to estimate the association of sex with the outcome and adjust for the candidate and donor factors. RESULTS: Women (N = 3019, 39.4%) spent equal time active at MELD 40 (median: 5 vs 5 days, P = 0.28) but had lower offer acceptance (9.2% vs 11.0%, P < 0.01) compared with men (N = 4635, 60.6%). Adjusting for candidate/donor factors, offers to women were less likely accepted (odds ratio = 0.87, P < 0.01). Adjusting for candidate factors, once they reached MELD 40, women were less likely to be transplanted (subdistribution hazard ratio = 0.90, P < 0.01) and more likely to die or be delisted (subdistribution hazard ratio = 1.14, P = 0.02). CONCLUSIONS: Even among candidates with high disease severity and equally high MELD scores, women have reduced access to liver transplantation and worse outcomes compared with men. Policies addressing this disparity should consider factors beyond MELD score adjustments alone.

Anterior Cervical Discectomy and Fusion With Structural Allograft is Associated With Lower Postoperative Health Care Utilization and Reoperations Compared With Cage Implants.

BACKGROUND AND OBJECTIVES: Implants represent a large component of surgical cost, with several available options for anterior cervical discectomy and fusion (ACDF). Rising ACDF volume highlights the need for accurate cost characterization among implant configurations to inform efficient utilization. METHODS: A cohort study of patients who underwent 1-level or 2-level ACDF in 2017 was conducted using the MarketScan national insurance databases, which contain deidentified clinical and financial data. Implant configurations included plate with cage, standalone cage, and plate with structural allograft. Patients who switched insurance providers within 2 years after surgery or underwent concurrent posterior cervical surgery, cervical disk arthroplasty, or cervical corpectomy were excluded. A combined plate/cage and standalone cage group was compared with the allograft group followed by the comparison of the plate/cage and standalone cage groups. In total, 30-day, 90-day, and 2-year aggregate costs; component costs of physical therapy, injections, medications, psychological treatment, and subsequent spine surgery; and reoperation rates were evaluated. RESULTS: Of 1723 patients identified, 360 (20.9%) underwent surgery with plate/cage, 184 (10.7%) with standalone cage, and 1179 (68.4%) with allograft. Aggregate costs were lower in the allograft group compared with the combined cage group at 90 days ($36 428 vs $39 875, P = .04) and 2 years ($64 951 vs $74 965, P = .005) postoperatively. There were no significant differences in aggregate costs between the plate/cage and standalone cage groups. The 2-year reoperation rate was higher in the combined cage compared with the allograft group (23.9% vs 10.9%, P < .001) and was also higher in the standalone cage compared with the plate/cage group (32.0% vs 19.7%, P = .002). CONCLUSION: Compared with alternative ACDF constructs, allograft is associated with lower postoperative costs and reoperation rates. Although costs are similar, reoperation rates are lower with plate/cage constructs compared with those of standalone cages. Surgeons should consider these financial and clinical differences when selecting implant configurations.

Minority-Serving Hospitals Are Associated With Low Within-Hospital Disparity.

BACKGROUND: Disparities in obstetric care have been well documented, but disparities in the within-hospital population have not been as extensively explored. The objective is to assess cesarean delivery rate disparities at the hospital level in a nationally recognized low risk of cesarean delivery group. METHODS: An observational study using a national population-based database, Nationwide Inpatient Sample, from 2008 to 2011 was conducted. All patients with nulliparous, term, singleton, vertex pregnancies from Black and White patients were included. The primary outcome was delivery mode (cesarean vs vaginal). The primary independent variable was race (Black vs White). RESULTS: A total of 1,064,351 patients were included and the overall nulliparous, term, singleton, and vertex pregnancies cesarean delivery rate was 14.1%. The within-hospital disparities of cesarean delivery rates were lower in minority-serving hospitals (OR: 1.20 95% CI: 1.12-1.28), rural hospitals (OR 1.11 95% CI: 1.02-1.20), and the South (OR 1.24 95% CI 1.19-1.30) compared to their respective counterparts. Non-minority serving hospitals (OR: 1.20 95% CI 0.12-1.25), and urban hospitals (OR1.32 95% CI 1.28-1.37), the Northeast (OR 1.41 95% CI 1.30-1.53) or West (OR 1.52 95% CI 1.38-1.67), had higher within-hospital racial disparities of cesarean delivery rates. The odds ratios reported are comparing within-hospital cesarean delivery rates in Black and White patients. DISCUSSION: Significant within-hospital disparities of cesarean delivery rates across hospitals highlight the importance of facility-level factors. Policies aimed at advancing health equity must address hospital-level drivers of disparities in addition to structural racism.

Caregiver-reported quality of communication in pancreatic and periampullary cancer.

BACKGROUND: Communication between caregivers and clinical team members is critical for transitional care, but its quality and potential impact on outcomes are not well understood. This study reports on caregiver-reported quality of communication with clinical team members in the postpancreatectomy period and examines associations of these reports with patient and caregiver outcomes. METHODS: Caregivers of patients with pancreatic and periampullary malignancies who had undergone pancreatectomy were surveyed. Instrument measures assessed care experiences using the Caregiver Perceptions About Communication with Clinical Team Members (CAPACITY) instrument. The instrument has two main subscales: communication, assessing the extent to which providers helped caregivers comprehend details of clinical visits, and capacity, defined as the extent to which providers assessed whether caregivers were able to care for patients. RESULTS: Of 265 caregivers who were approached, 240 (90.6%) enrolled in the study. The mean communication and capacity subscale scores were 2.7 ± 0.6 and 1.5 ± 0.6, respectively (range, 0-4 [higher = better]). Communication subscale scores were lower among caregivers of patients who experienced (vs. those who did not experience) a 30-day readmission (2.6 ± 0.5 vs. 2.8 ± 0.6, respectively; p = .047). Capacity subscale scores were inversely associated with restriction in patient daily activities (a 0.04 decrement in the capacity score for every 1 point in daily activity restriction; p = .008). CONCLUSIONS: After pancreatectomy, patients with pancreatic and periampullary cancer whose caregivers reported worse communication with care providers were more likely to experience readmission. Caregivers of patients with greater daily activity restrictions were less likely to report being asked about the caregiver's skill and capacity by clinicians. PLAIN LANGUAGE SUMMARY: This prospective study used a validated survey instrument and reports on the quality of communication between health care providers and caregivers as reported by caregivers of patients with pancreatic and periampullary cancer after pancreatectomy. In an analysis of 240 caregivers enrolled in the study, lower communication scores (the extent to which providers helped caregivers understand clinical details) were associated with higher odds of 30-day patient readmission to the hospital. In addition, lower capacity scores (the extent to which providers assessed caregivers' ability to care for patients) were associated with greater impairment in caregivers. The strikingly low communication quality and capacity assessment scores suggest substantial room for improvement, with the potential to improve both caregiver and patient outcomes.

Arthroscopic Procedures Are Performed in 5% of Patients With Knee Osteoarthritis 1 Year Preceding Total Knee Arthroplasty and Are Associated With Increased Stiffness and Increased Costs.

Purpose: To describe the different types of arthroscopic procedures that patients undergo in the year prior to total knee arthroplasty (TKA), reveal the cost associated with these procedures, and understand the relationship between preoperative arthroscopy and clinical outcomes after TKA. Methods: An observational cohort study was conducted using the IBM Watson Health MarketScan databases. Patients with knee osteoarthritis who underwent unilateral isolated primary TKA between January 1, 2018, and September 30, 2019, were included. Knee arthroscopic procedures performed in the 1-year period before a primary TKA was identified. The primary outcomes of interest were cost of these procedures and the risk of 90-day postoperative complications. Results: In total, 2,904 patients, representing 5.2% of the analyzed cohort, underwent arthroscopic procedures in the year prior to TKA. The most common procedure and diagnosis were meniscectomy and meniscal tear, respectively, with procedures performed an average of 7.2 ± 3.0 months before TKA. Average per patient costs were $9,716 ± $5,500 in the highest payment quartile vs $1,789 ± 636 in the lowest payment quartile. Patients with a history of arthroscopy were more likely to develop postoperative stiffness (P = .001), while no difference was found in the risk of 90-day periprosthetic joint infection (PJI). Conclusions: Of the patients, 5.2% underwent knee arthroscopy in the year prior to TKA. While no association was seen with PJI risk, the costs associated with these procedures are high and may increase the overall cost of management of knee osteoarthritis. Level of Evidence: Level III, retrospective comparative study.

Public health insurance, frailty, and lack of home support predict rehab discharge following elective anterior cervical discectomy and fusion.

BACKGROUND CONTEXT: Anterior cervical discectomy and fusion (ACDF) is a commonly-performed and generally well-tolerated procedure used to treat cervical disc herniation. Rarely, patients require discharge to inpatient rehab, leading to inconvenience for the patient and increased healthcare expenditure for the medical system. PURPOSE: The objective of this study was to create an accurate and practical predictive model for, as well as delineate associated factors with, rehab discharge following elective ACDF. STUDY DESIGN: This was a retrospective, single-center, cohort study. PATIENT SAMPLE: Patients who underwent ACDF between 2012 and 2022 were included. Those with confounding diagnoses or who underwent concurrent, staged, or nonelective procedures were excluded. OUTCOME MEASURES: Primary outcomes for this study included measurements of accuracy for predicting rehab discharge. Secondary outcomes included associations of variables with rehab discharge. METHODS: Current Procedural Terminology codes identified patients. Charts were reviewed to obtain additional demographic and clinical characteristics on which an initial univariate analysis was performed. Two logistic regression and two machine learning models were trained and evaluated on the data using cross-validation. A multimodel logistic regression was implemented to analyze independent variable associations with rehab discharge. RESULTS: A total of 466 patients were included in the study. The logistic regression model with minimum corrected Akaike information criterion score performed best overall, with the highest values for area under the receiver operating characteristic curve (0.83), Youden's J statistic (0.71), balanced accuracy (85.7%), sensitivity (90.3%), and positive predictive value (38.5%). Rehab discharge was associated with a modified frailty index of 2 (p=.007), lack of home support (p=.002), and having Medicare or Medicaid insurance (p=.007) after correction for multiple hypotheses. CONCLUSIONS: Nonmedical social determinants of health, such as having public insurance or a lack of support at home, may play a role in rehab discharge following elective ACDF. In combination with the modified frailty index and other variables, these factors can be used to predict rehab discharge with high accuracy, improving the patient experience and reducing healthcare costs.

Workforce Attrition Among Male and Female Physicians Working in US Academic Hospitals, 2014-2019.

Importance: Retaining female physicians in the academic health care workforce is necessary to serve the needs of sociodemographically diverse patient populations. Objective: To investigate differences in rates of leaving academia between male and female physicians. Design, Setting, and Participants: This cohort study used Care Compare data from the Centers for Medicare & Medicaid Services for all physicians who billed Medicare from teaching hospitals from March 2014 to December 2019, excluding physicians who retired during the study period. Data were analyzed from November 11, 2021, to May 24, 2022. Exposure: Physician gender. Main Outcome and Measures: The primary outcome was leaving academia, which was defined as not billing Medicare from a teaching hospital for more than 1 year. Multivariable logistic regression was conducted adjusting for physician characteristics and region of the country. Results: There were 294 963 physicians analyzed (69.5% male). The overall attrition rate from academia was 34.2% after 5 years (38.3% for female physicians and 32.4% for male physicians). Female physicians had higher attrition rates than their male counterparts across every career stage (time since medical school graduation: <15 years, 40.5% vs 34.8%; 15-29 years, 36.4% vs 30.3%; ≥30 years, 38.5% vs 33.3%). On adjusted analysis, female physicians were more likely to leave academia than were their male counterparts (odds ratio, 1.25; 95% CI, 1.23-1.28). Conclusions and Relevance: In this cohort study, female physicians were more likely to leave academia than were male physicians at all career stages. The findings suggest that diversity, equity, and inclusion efforts should address attrition issues in addition to recruiting more female physicians into academic medicine.

Time to surgery: A health equity metric in breast cancer patients.

BACKGROUND: We evaluated whether time to surgery by race can be a health equity metric of surgical access. METHODS: An observational analysis was performed using the National Cancer Database from 2010 to 2019. Inclusion criteria were women with stage I-III breast cancer. We excluded women with multiple cancers and whose diagnosis was made at a different hospital. The primary outcome variable was surgery within 90 days of diagnosis. RESULTS: A total of 886,840 patients were analyzed, with 76.8% White and 11.7% Black patients. 11.9% of patients experienced delayed surgery, which was significantly more common in Black patients than White patients. On adjusted analysis, Black patients were still significantly less likely to receive surgery within 90 days when compared to White patients (OR 0.61, 95% CI 0.58-0.63). CONCLUSION: The delay in surgery experienced by Black patients highlights the contribution of system factors in cancer inequity and should be a focus for targeted interventions.

Greater Patient Travel Distance is Associated with Perioperative and One-Year Cost Increases After Complex Aortic Surgery.

BACKGROUND: With increasing regionalization of complex aortic surgery within fewer US centers, patients may face increased travel burden when accessing aortic surgery. Longer travel distances have been associated with inferior outcomes after major surgery; however, the impacts of distance on reinterventions and costs have not been described. This study aims to assess the association between patient travel distance and longer-term outcomes including costs and reinterventions after complex aortic surgery. METHODS: A retrospective review was conducted of all patients in the Vascular Implant Surveillance and Interventional Outcomes Network database undergoing complex endovascular aortic repair including internal iliac or visceral vessel involvement, complex thoracic endovascular aortic repair including Zone 0-2 proximal extent or branched devices, and complex open abdominal aortic aneurysm repair including suprarenal or higher clamp sites. Travel distance was stratified by Rural-Urban Commuting Area population-density category. Multinomial logistic regression models, negative-binomial models, and zero-inflated Poisson models were used to assess the association between travel distance and index procedural and comprehensive first-year costs, long-term imaging, and long-term reinterventions, respectively. RESULTS: Between 2011 and 2018, 8,782 patients underwent complex aortic surgery in the Vascular Implant Surveillance and Interventional Outcomes Network database, including 4,822 complex endovascular aortic repairs, 2,672 complex thoracic endovascular aortic repairs, and 1,288 complex open abdominal aortic aneurysm repairs. Median travel distance was 22.8 miles (interquartile range 8.6-54.8 miles, range 0-2,688.9 miles). Median age was 75 years for all distance quintiles. Patients traveling farther were more likely to be female (26.8% in quintile 5 [Q5] vs. 19.9% in Q1, P < 0.001) and to have had a prior aortic surgery (20.8% for Q5 vs. 5.9% for Q1, P < 0.001). Patients traveling farther had higher index procedural costs, with adjusted odds ratio (OR) 2.34 (95% confidence interval [CI] 1.86-2.94, P < 0.0001) of being in the highest cost tertile versus lowest for patients in Q5 vs. Q1. For patients with ≥ 1-year follow-up, those traveling farther had higher imaging costs, with adjusted Q5 OR 1.55 (95% CI 1.22-1.95, P = 0.0002), and comprehensive first-year costs, with adjusted Q5 OR 2.06 (95% CI 1.57-2.70, P < 0.0001). In contrast, patients traveling farther had similar numbers of reinterventions and imaging studies postoperatively. CONCLUSIONS: Patients traveling farther for complex aortic surgery have higher procedural costs, postoperative imaging costs, and comprehensive first-year costs. These patients should be targeted for increased care coordination for improved outcomes and healthcare system burden.

Early vs Delayed Transurethral Surgery in Acute Urinary Retention: Does Timing Make a Difference?

PURPOSE: Our goal was to compare outcomes of early vs delayed transurethral surgery for benign prostatic hyperplasia after an episode of acute urinary retention compared to men without preoperative acute retention. MATERIALS AND METHODS: We conducted a retrospective cohort analysis using data from the New York Statewide Planning and Research Cooperative System from 2002-2016. We identified men ≥40 years old who underwent primary ambulatory transurethral resection or photoselective vaporization of the prostate, assessing surgical failure as time to reoperation or recatheterization. We categorized presurgical acute urinary retention by number of episodes: none (reference), 1, or ≥2 precatheterizations, and time from first retention episode to surgery: none (reference), 0-6 months, and >6 months. We used Fine-Gray competing-risk models to predict surgical failure at 10 years, with presurgical acute retention as the primary predictor, adjusted for age, race, insurance, Charlson Comorbidity Index score, preoperative urinary infection, and procedure type, with death as the competing risk. RESULTS: Among 17,474 patients undergoing transurethral surgery, 10% had preoperative acute retention with a median time to surgery of 2.4 months (IQR: 1-18). Among men with preoperative retention, 37% had ≥6 months of delay to surgery. The 10-year cumulative treatment failure rate was 17.2% among catheter naïve men vs 34.0% with ≥2 precatheterizations and 32.9% with ≥6 months delay to surgery. Delays from catheterization to surgery were associated with higher rates of treatment failure (<6 months SHR 1.49, P < .001; ≥6 months SHR 2.11, P < .001) vs catheter naïve men. CONCLUSIONS: Preoperative acute urinary retention and delay to surgery once catheterized are associated with poorer long-term postoperative outcomes after surgery for benign prostatic hyperplasia.

Profile of the Postoperative Care Provided for Patients With Pancreatic and Periampullary Cancers by Family and Unpaid Caregivers.

PURPOSE: Patients with pancreatic and periampullary cancers may experience significant reduction in their quality of life and often rely on family and unpaid caregivers for assistance after surgery. However, as caregivers are not systematically identified, little is known about the nature, difficulty, and personal demands of assistance they provide. We aim to assess the frequency and difficulty of specific assistance caregivers provide and identify potential interventions that could alleviate the caregiving demands. METHODS: This was a prospective, multi-institutional study of caregivers accompanying patients with periampullary and pancreatic cancer at their 1-month postpancreatectomy office visit. An instrument that drew heavily on the National Study of Caregiving was administered to caregivers. RESULTS: Of 240 caregivers, more than half (58.3%) of caregivers were the patients' spouse, a quarter (25.8%) were daughters or sons, 12.9% other relatives, and 2.9% nonrelatives. Caregivers least frequently provided assistance with transportation (14.6% every day) and most frequently provided assistance with housework (65.0% every day, P = .003) and diet (56.5% every day, P = .004). Caregivers reported the least difficulty helping patients with exercise (1.5% somewhat difficult). Caregivers reported significantly more difficulty with assisting with housework (14.5% somewhat difficult, P < .001) and diet (14.9% somewhat difficult, P < .001). Caregivers identified the immediate postpancreatectomy and early discharge periods as the most stressful phases. They also reported having received very little information about available services that could have supported their efforts. CONCLUSION: Caregivers of patients with periampullary or pancreatic cancer provide considerable assistance in the postoperative period and many reported difficulty in assisting with housework and diet. Work is needed to better prepare and support caregivers to better enable them to adequately care for patients with pancreas and periampullary cancer.

Reducing Sharps Injuries in the Operating Rooms of an Academic Tertiary Care Center.

BACKGROUND: Data on the prevalence and distribution of operating room (OR) sterile field sharps injuries sustained by attending surgeons, residents, scrub nurses, and surgical technologists are limited. The goal of this study is to understand current practices, injuries, and reporting behavior at an academic center, implement interventions, and assess their effect on sharps safety and reporting. METHODS: An electronic survey with questions pertaining to sharps handling practices, injuries, and reporting was e-mailed to 864 staff between July and September 2014. Adjusted analyses for risk of injury were performed. A follow-up survey was sent in January 2018, following the implementation of a shorter injury reporting form and a neutral zone. RESULTS: The overall response rate was 49.3%, with 363 completed surveys. Of respondents, 44.9% reported injuries occurring in the preceding three years. Physicians comprised 65.1% of injured staff and sustained 68.8% of the total injuries. Compared to attending surgeons, residents had a similar likelihood of injury (odds ratio 0.9, 95% confidence interval [CI] 0.37-2.2), whereas scrub nurses (odds ratio 0.3, 95% CI 0.17-0.54) and technologists (odds ratio 0.3, 95% CI 0.14-0.76) had a lower likelihood. Half of those injured reported to Occupational Health Services. Of those who did not report, 46.4% stated that time was a limiting factor. Following the interventions, the incidence of injuries among survey respondents remained unchanged. However, 54.0% of respondents stated that it was easier to report injuries. CONCLUSION: Attending surgeons and residents sustain the majority of OR sterile field sharps injuries and are the least likely to report them. Shorter reports made it easier to report the injuries.

The Effect of Language on Access to Timely COVID-19 Vaccination of Solid Abdominal Organ Transplant Recipients.

In dynamic healthcare environments including the COVID-19 pandemic, it is paramount to communicate health recommendations expediently and clearly. Research has shown social determinants of health affect the impact of COVID-19 on abdominal transplant recipients, but there has been less research on the effect of language proficiency. This is a cohort study of time to first COVID-19 vaccination among abdominal organ transplant recipients in an academic medical center in Boston, MA between 18 December 2020, and 15 February 2021. Cox proportional hazards analysis of time to vaccination by preferred language were adjusted for race, age group, insurance, and transplanted organ. Among 3001 patients, 53% were vaccinated during the study period. Language preference other than English was independently associated with delay to vaccination (0.64, p = 0.001), on adjusted analysis. In addition, Black, Hispanic and other race patients were less likely to be vaccinated than white patients (0.58, 0.67, 0.68 vs. reference, all p < 0.03). Language preference other than English is an independent barrier to solid abdominal organ transplant recipients' access to timely COVID-19 vaccination. Equity in care should be improved by providing targeted services to minority language speakers.

External validation of the Codman score in colorectal surgery: a pragmatic tool to drive quality improvement.

AIM: The simple six-variable Codman score is a tool designed to reduce the complexity of contemporary risk-adjusted postoperative mortality rate predictions. We sought to externally validate the Codman score in colorectal surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) participant user file and colectomy targeted dataset of 2020 were merged. A Codman score (composed of six variables: age, American Society of Anesthesiologists score, emergency status, degree of sepsis, functional status and preoperative blood transfusion) was assigned to every patient. The primary outcome was in-hospital mortality and secondary outcome was morbidity at 30 days. Logistic regression analyses were performed using the Codman score and the ACS NSQIP mortality and morbidity algorithms as independent variables for the primary and secondary outcomes. The predictive performance of discrimination area under receiver operating curve (AUC) and calibration of the Codman score and these algorithms were compared. RESULTS: A total of 40 589 patients were included and a Codman score was generated for 40 557 (99.02%) patients. The median Codman score was 3 (interquartile range 1-4). To predict mortality, the Codman score had an AUC of 0.92 (95% CI 0.91-0.93) compared to the NSQIP mortality score 0.93 (95% CI 0.92-0.94). To predict morbidity, the Codman score had an AUC of 0.68 (95% CI 0.66-0.68) compared to the NSQIP morbidity score 0.72 (95% CI 0.71-0.73). When body mass index and surgical approach was added to the Codman score, the performance was no different to the NSQIP morbidity score. The calibration of observed versus expected predictions was almost perfect for both the morbidity and mortality NSQIP predictions, and only well fitted for Codman scores of less than 4 and greater than 7. CONCLUSION: We propose that the six-variable Codman score is an efficient and actionable method for generating validated risk-adjusted outcome predictions and comparative benchmarks to drive quality improvement in colorectal surgery.
